3 General principles

3.1 Measurement principle
General principles
In the ultrasonic flow measurement, the flow velocity of the fluid in a pipe is determined. Further physical quantities are derived from the flow velocity and from additional physical quantities, if necessary.
3.1
Measurement principle
The flow velocity of the fluid is measured in the TransitTime mode using the ultrasonic-transit time difference correlation
principle. When measuring with a high proportion of gas or solid particles, the transmitter can toggle into the NoiseTrek
mode.
3.1.1
Terms
Flow profile
Distribution of flow velocities over the cross-sectional pipe area. For an optimal measurement, the flow profile has to be
fully developed and axisymmetrical. The shape of the flow profile depends on whether the flow is laminar or turbulent and
is influenced by the conditions at the inlet of the measuring point.
Reynolds number Re
Coefficient describing the turbulence behavior of a fluid in the pipe. The Reynolds number Re is calculated from the flow
velocity, the kinematic viscosity of the fluid and the inner pipe diameter.
If the Reynolds number exceeds a critical value (usually approx. 2300, if the fluid flows in a pipe), a transition from a laminar flow to a turbulent flow takes place.
Laminar flow
A flow without any turbulence. There is no mixing between the parallel flowing layers of the fluid.
Turbulent flow
A flow with turbulences (swirling of the fluid). In technical applications, the flow in the pipe is mostly turbulent.
Transition range
The flow is partly laminar and partly turbulent.
Sound speed c
Speed of the propagating sound. The sound speed depends on the mechanical properties of the fluid or the pipe material.
In pipe materials and other solid materials, a distinction is made between the longitudinal and transversal sound speed.
For the sound speed of some fluids and materials, see annex C.
Flow velocity v
Average value of all flow velocities of the fluid over the cross-sectional pipe area.
Acoustic calibration factor ka
c

ka = ----------sin 
The acoustic calibration factor ka is a transducer parameter which results from the sound speed c within the transducer
and the angle of incidence. According to Snell's law of refraction, the angle of propagation in the adjoining fluid or pipe material is:
c

- = ----------- = ---------ka = ----------sin 

sin 
Fluid mechanics correction factor kRe
With the fluid mechanics calibration factor kRe, the measured value of the flow velocity in the area of the sound beam is
converted into the value of the flow velocity across the whole cross-sectional pipe area. In case of a fully developed flow
profile, the fluid mechanics calibration factor only depends on the Reynolds number and the roughness of the inner pipe
wall. The fluid mechanics calibration factor is recalculated by the transmitter for each new measurement.
·
Volumetric flow rate V
·
V =v·A
The volume of the fluid that passes through the pipe per unit time. The volumetric flow rate is calculated from the product
of the flow velocity v and the cross-sectional pipe area A.

m
The mass of the fluid that passes through the pipe per unit time. The mass flow rate is calculated from the product of the

volumetric flow rate V and the density ρ.
3.1.2
Measurement of the flow velocity in the TransitTime mode
The signals are emitted and received by 2 transducers alternatively in and against the flow direction. If the fluid is flowing,
the signals propagating in the fluid are displaced with the flow.
Caused by this displacement, the sound path of the signal in flow direction is reduced and the signal against the flow direction is increased, see Fig. 3.1 and Fig. 3.2.
This causes a change in the transit times. The transit time of the signal in flow direction is shorter than the transit time
against the flow direction. The transit time difference is proportional to the average flow velocity.
The average flow velocity of the fluid is calculated as follows:
t
v = kRe · ka · ---------2t

3.1.3
Measurement of the flow velocity in the NoiseTrek mode
If the proportion of gas or solids in the fluid is high, the damping of the ultrasonic signal can be so high that the complete
propagation of the fluid and therefore a measurement in TransitTime mode is not possible anymore. In this case the
NoiseTrek mode has to be used.
The NoiseTrek mode uses the presence of gas bubbles and/or solid particles in the fluid.
Ultrasonic signals are sent from a transducer into the fluid at short intervals, reflected by the gas bubbles and/or the solids
particles and again received by the same transducer.
The measurement arrangement used in the TransitTime mode does not need to be changed.
The transit time difference t of 2 consecutive ultrasonic signals is determined. It behaves proportionately to the distance
the gas bubble/solid particle is covering between 2 consecutive pulses and thus, to the average flow velocity of the fluid,
see Fig. 3.4.

The average flow velocity of the fluid is calculated as follows:

kRe

ka

Δtp
– time difference between 2 consecutive pulses
Δt
– transit time difference of ultrasonic signals S1 and S2 (Δt = t2 - t1)
Depending on the attenuation of the ultrasonic signal, the error of measurement in the NoiseTrek mode can be greater
than in the TransitTime mode.

3.2 Measurement arrangements
3.1.4
FLUXUS F808
Measurement of the flow velocity in the HybridTrek mode
The HybridTrek mode combines the TransitTime and the NoiseTrek mode. During a measurement in the HybridTrek
mode, the transmitter automatically toggles between the TransitTime and the NoiseTrek mode depending on the gaseous
or solid content.
The measurement arrangement is identical to the one in the TransitTime mode.
3.1.5
Measurement of the flow velocity in the NoiseTrek parallel beam mode
Pipes with a small pipe diameter or fluids which strongly attenuate the ultrasonic signal can cause a reduction of the transit
time in the fluid with the result that the signal quality is no longer sufficient. In this case the NoiseTrek parallel beam mode
has to be used.
The NoiseTrek parallel beam mode works the same way the NoiseTrek mode does, the only difference is that the sending
and receiving process do not occur in the same transducer. This leads to a better signal quality. The transducers are
mounted in parallel on the pipe at a small distance, see Fig. 3.5.
A measurement in TransitTime mode is not possible when working with this measurement arrangement.

3.3 Acoustic penetration
3.3
FLUXUS F808
Acoustic penetration
The pipe has to be acoustically penetrable at the measuring point. The acoustic penetration is given when pipe and fluid
do not attenuate the sound signal so strongly that it is completely absorbed before reaching the second transducer.
The attenuation caused by the pipe and the fluid depends on:
• kinematic viscosity of the fluid
• proportion of gas bubbles and solids in the fluid
• deposits on the inner pipe wall
• pipe material
The following requirements have to be met at the measuring point:
• the pipe is always completely filled
• no solid deposits in the pipe
• no bubble formation in the pipe
Notice!
Even bubble-free fluids can form gas bubbles when the fluid expands, e.g., before pumps and after great cross-section
extensions.
Observe the following notes on the selection of the measuring point:
Horizontal pipe
Select a measuring point where the transducers can be mounted laterally on the pipe, allowing the sound waves to propagate horizontally in the pipe. Thus, solids on the bottom of the pipe or gas bubbles in the pipe's upper part are prevented
from influencing the propagation of the signal, see Fig. 3.9 and Fig. 3.10.

Undisturbed flow profile

Some flow elements (e.g., elbows, valves, pumps, reducers) distort the flow profile in their vicinity. The axisymmetrical
flow profile in the pipe needed for correct measurement is no longer given. A careful selection of the measuring point helps
to reduce the impact of disturbance sources.
It is most important that the measuring point is chosen at a sufficient distance from any disturbances. Only then it can be
assumed that the flow profile in the pipe is fully developed. However, measuring results can be obtained even if the
recommended distance to disturbances cannot be met for practical reasons (no ideal inflow, see section 16.6).
The recommended straight inlet and outlet pipe lengths for different types of flow disturbance sources are shown in the
examples in Tab. 3.1.

Measuring point selection
6
Installation
The correct selection of the measuring point is crucial for achieving reliable measurement results and a high measurement
accuracy.
A measurement on a pipe is possible if:
• the ultrasound propagates with a sufficiently high amplitude
• the flow profile is fully developed
The correct selection of the measuring point and the correct transducer positioning guarantee that the sound signal will be
received under optimum conditions and evaluated correctly.
Because of the variety of applications and the different factors that influence the measurement, there is no standard solution for the transducer positioning.
The measurement is influenced by the following factors:
– diameter, material, lining, wall thickness and shape of the pipe
– fluid
– gas bubbles in the fluid
• Avoid measuring points in the vicinity of distorted or defective areas of the pipe or in the vicinity of welds.
• Avoid measuring points with deposit formation in the pipe.
• Make sure the pipe surface at the selected measuring point is even.
• Select the location of the transmitter within the transducer cable range.
• The ambient temperature at the measuring point has to be within the operating temperature range of the transmitter and
the transducers, see technical specification.
If the measuring point is within an explosive atmosphere, possibly present danger zones and gases have to be determined. The transducers and the transmitter have to be appropriate for these conditions.
6.2.1.2
Pipe preparation
Caution!
Contact with grinding dust
This may result in injuries (e.g., breathing difficulties, skin reactions, eye irritations).
→ Wear the required personal protective equipment. Observe the applicable rules.
Important!
The pipe has to be sufficiently stable to withstand the pressure exerted by the transducers and the tension straps.
Notice!
Observe the selection criteria of pipe and measuring point.
Rust, paint or deposits on the pipe absorb the sound signal. A good acoustic contact between the pipe and the transducers is obtained as follows:
• Clean the pipe at the selected measuring point.
– If present, the paint layer has to be smoothed by grinding. The paint does not need to be removed completely.
– Remove rust or loose paint.
• Use coupling foil or apply a bead of acoustic coupling compound along the center line of the contact surface of the transducers.
• Observe that there must be no air pockets between the transducer contact surface and the pipe wall.

Selection of the measurement arrangement
Diagonal arrangement with 1 beam
Reflection arrangement with 1 beam
• wider flow velocity and sound speed
range compared to the reflection
arrangement
• use in the presence of deposits on the inner pipe wall or with strongly attenuating
gases or liquids (only 1 sound path)
• smaller flow velocity and sound speed
range compared to the diagonal
arrangement
• transverse flow effects are compensated
because the beam crosses the pipe in 2
directions
• higher accuracy of measurement
because the accuracy increases with the
number of sound paths
If the measuring point is situated near an elbow, the following measurement arrangements are recommended for the
selection of the sound beam plane.
Vertical pipes

Connection with potential separation
If earthing on the same potential cannot be ensured e.g., in measurement arrangements with long extension cables, the
extension cable and the junction box have to be electrically insulated from each other. The junction box and the transducers have to be on the same potential. By doing this, no compensation currents can flow to the transmitter via the extension
cables.
For measurement arrangements where the junction box and the transducers have to be electrically insulated from each
other, see the document TIFLUXUS_GalvSep.
• Remove the blind plug for the connection of the extension cable.
• Open the cable gland of the extension cable. The compression part remains in the cap nut.
• Push the extension cable through the cap nut, the compression part and the basic part.
• Insert the extension cable into the junction box.
• Prepare the extension cable.
• Cut the outer shield and brush it back.
• Pull the extension cable back until the back brushed external shield is below the shield terminal, see Fig. 7.9. The extension cable has to remain completely insulated up to the shield terminal.
• Screw the gasket ring side of the basic part into the junction box.
• Fix the cable gland by screwing the cap nut onto the basic part.
Important!
Observe the max. permissible voltage of 60 V DC between the earth potentials.
Important!
The external shield of the extension cable must not have electrical contact to the junction box. Therefore, the extension cable has to remain completely insulated up to the shield terminal.
• Fix the extension cable and the external shield to the shield terminal.

Connection
The installation of the power supply is carried out by the operator. The operator has to provide an overcurrent protector
(fuse or similar device) disconnecting all energizing wires in case of an inadmissible high current consumption. The impedance of the protective earth has to be low ohmic in order not to allow touch voltage pass the permissible limit. The equipotential bonding terminal serves as functional earth of the transmitter, see Fig. 7.19.
The external protective earth is connected to the equipotential bonding terminal on the transmitter housing.
Important!
The degree of protection of the transmitter will only be guaranteed if the power cable fits firmly and tightly in the cable
gland.
• Connect the power cable to the transmitter.

10 Troubleshooting
10.1 Problems with the measurement
10.1
FLUXUS F808
Problems with the measurement
A measurement is not possible because no signal is received. A question mark is displayed after the physical
quantity.
• Check whether the entered parameters are correct, especially the outer pipe diameter, the pipe wall thickness and the
sound speed of the fluid. Typical errors: The circumference or the radius was entered instead of the diameter. The inner
pipe diameter was entered instead of the outer pipe diameter.
• Check the number of sound paths.
• Make sure that the recommended transducer distance was adjusted when mounting the transducers.
• Make sure that an appropriate measuring point is selected and the number of sound paths was entered correctly.
• Try to establish a better acoustic contact between the pipe and the transducers.
• Enter a lower value for the number of sound paths. The signal attenuation might be too high due to a high fluid viscosity
or deposits on the inner pipe wall.
The measuring signal is received but no measured values can be obtained
• A exclamation point (!) in the lower line on the right indicates that the defined upper limit of the flow velocity is exceeded
and, therefore, the measured values are marked as invalid. The limit has to be adapted to the measuring conditions or
the check has to be deactivated.
• If no exclamation point is displayed, a measurement at the selected measuring point is impossible.
Signal loss during the measurement
• If there is no measuring signal after the pipe had been run empty and refilled, contact FLEXIM.
• Wait a moment until the acoustic contact is reestablished. The measurement can be interrupted due to a temporarily
higher proportion of gas bubbles and solids in the fluid.
The measured values substantially differ from the expected values
• Wrong measured values are often caused by wrong parameters. Make sure that the entered parameters are correct for
the measuring point.
10.2
Measuring point selection
• Make sure that the recommended min. distance to any disturbance source is observed.
• Avoid measuring points with deposit formation in the pipe.
• Avoid measuring points in the vicinity of deformations and defects on the pipe as well as welds.
• Make sure the pipe surface at the selected measuring point is even.
• Measure the temperature at the measuring point and make sure that the transducers are suitable for this temperature.
• Make sure that the outer pipe diameter is within the measuring range of the transducers.
• When measuring on a horizontal pipe, the transducers have to be mounted laterally on the pipe.
• The measuring point on a vertically mounted pipe has always to be filled. The fluid should flow upward.
• No gas bubbles should form (even bubble-free fluids can form gas bubbles when the fluid expands, e.g., upstream of
pumps and downstream of great cross-section enlargements).
10.3
Maximum acoustic contact
see section 6.2
10.4
Application-specific problems
A fluid with a wrong sound speed was selected
If the selected sound speed in the fluid does not match the actual one, the transducer distance can probably not be determined correctly.
The fluid sound speed is used to calculate the transducer distance and is therefore very important for the transducer positioning. The sound speeds stored in the transmitter only serve as an orientation.
The entered pipe roughness is not appropriate
Check the entered value. The pipe state should be considered.
Measurements on pipes made of porous materials (e.g., concrete or cast iron) are only conditionally possible
Contact FLEXIM.

10.5 Significant deviations of the measured values
The pipe lining may cause problems during the measurement if it is not firmly attached to the inner pipe wall or
consists of acoustically absorbing material
Try to measure on a section of the pipe free from lining.
Highly viscous fluids strongly attenuate the ultrasonic signal
The measurement of fluids with a viscosity of > 1000 mm²/s is only conditionally possible.
A high concentration of gases or solids in the fluid scatter and absorb the ultrasonic signal and thus attenuate
the measuring signal
A measurement is impossible if the value is ≥ 10 %. If the proportion is high, but < 10 %, a measurement is only conditionally possible.
10.5
Significant deviations of the measured values
A fluid with a wrong sound speed was selected
If a fluid was selected whose sound speed does not match the actual one, the measuring signal may be confused with the
pipe wall signal.
The flow calculated on the basis of the wrong signal by the transmitter is very small or fluctuates around zero.
There is gas in the pipe
If there is gas in the pipe, the measured flow will be too high because both, the liquid and gas volume, are measured.
The defined upper limit of the flow velocity is too low
All measured flow velocities that are greater than the upper limit will be ignored and marked as invalid. All quantities deviated from the flow velocity will also be indicated as invalid. If several correct measured values are ignored, the totalizer
values will be too low.
The entered cut-off flow is too high
All flow velocities below the cut-off flow are set to zero. All derived quantities are also set to zero. The cut-off flow has to be
set to a low value to be able to measure at low flow velocities (default: 2.5 cm/s).
The entered pipe roughness is not appropriate
The flow velocity of the fluid is outside the measuring range of the transmitter
The measuring point is not appropriate
Check whether a different measuring point provides better results. Because pipes are never rotationally symmetric, the
flow profile is affected.
10.6
Problems with the totalizers
The values of the totalizers are too high
See Special Funct.\SYSTEM settings\Measuring\Quantity recall. If this menu item is activated, the values
of the totalizer will be stored. The totalizer will continue with this value at the start of the next measurement.
The values of the totalizers are too small
One of the totalizers has reached the upper limit and has to be reset to zero manually.
The sum of the totalizers is not correct
See Special Funct.\SYSTEM settings\Measuring\Quant. wrapping. The sum of both totalizers (throughput)
transmitted via the output is no longer valid after the first overflow (wrapping) of one of the totalizers.

If no measurement is possible in the TransitTime mode within 40 s, the transmitter toggles to the NoiseTrek mode. If no
measurement is possible in the NoiseTrek mode within 60 s, the transmitter toggles back to the TransitTime mode.
If valid measured values are obtained during the measurement in the NoiseTrek mode, the transmitter toggles to the
TransitTime mode every 300 s. If no measurement is possible in the TransitTime mode for the duration of 5 s, the transmitter toggles back to the NoiseTrek mode. If a valid measured value is obtained in the TransitTime mode within 5 s, the
transmitter continues the measurement in the TransitTime mode.

Upper limit of the flow velocity
Single outliers caused by heavily disturbed surroundings can appear among the measured values of the flow velocity. If
these outliers are not ignored, they will affect all derived physical quantities, which will be unsuitable for the integration
(e.g., pulse outputs).
It is possible to ignore all measured flow velocities exceeding the preset upper limit. These measured values will be
marked as outliers.
The upper limit of the flow velocity is set in Special Funct.\SYSTEM settings\Measuring\Velocity limit.

• Select the physical quantity to be used for the comparison in the scroll list Input. The following list items are available
for the alarm output R1:
– selected physical quantity
– signal amplitude
– sound speed of the fluid
• Press ENTER.
For the alarm outputs R2 and R3 the current physical quantity is set automatically.
If the switching condition MAX is selected in the scroll list func:

mass flow rate = -9.9 kg/h
the limit is exceeded, the alarm switches
mass flow rate = -11 kg/h
the limit is not exceeded, the alarm does not switch
Example
Low Limit: -10 kg/h
mass flow rate = -11 kg/h
the measured value is below the limit, the alarm switches
mass flow rate = -9.9 kg/h

The unit of measurement of the physical quantity is changed to kg/min. The new limit to be entered is 1 kg/min.
16.12.3 Defining the hysteresis
A hysteresis can be defined for the alarm output R1. This prevents a constant triggering of the alarm when measured
values fluctuate marginally around the limit.
The hysteresis is a symmetrical range around the limit. The alarm will be activated if the measured values exceed the
upper limit and deactivated if the measured values fall below the lower limit.
Example
High Limit: 30 kg/h
Hysterese: 1 kg/h
The alarm is activated for measured values > 30.5 kg/h and deactivated for measured values < 29.5 kg/h.

At the beginning of the transducer positioning (bar graph display), all alarm outputs switch back to the programmed idle
state.
If the bar graph is selected during the measurement, all alarm outputs will switch back to the programmed idle state.
An alarm output of the type HOLD that has been activated during the previous measurement will remains in idle state after
the transducer positioning if its switching condition is no longer met.
The switching of the alarms into idle state will not be displayed.
16.13.4 Alarm outputs during measurement
An alarm output with switching condition MAX or MIN will be updated max. once per second to avoid humming (i.e. fluctuation of the measured values around the value of the switching condition).
An alarm output of the type NON-HOLD will be activated if the switching condition is met. It will be deactivated if the switching condition is no longer met. The alarm remains activated for at least 1 s even if the switching condition is met for a
shorter period of time.
Alarm outputs with the switching condition QUANT. will be activated if the limit is reached.
Alarm outputs with the switching condition ERROR will only be activated after several unsuccessful measuring attempts.
Therefore, typical short-term disturbances of the measurement (e.g., switching on of a pump) will not activate the alarm.
Alarm outputs with the switching condition +→- -→+ and the type NON-HOLD will be activated with each change of the flow
direction for approx. 1 s, see Fig. 16.1.
Alarm outputs with the switching condition +→- -→+ and of the type HOLD will be activated after the first change of the flow
direction. They can be switched back by pressing key CLR 3 times, see Fig. 16.1.

• Enter the offset. Enter zero to work without offset.
• Press ENTER.
Example
Slope: 1.1
Offset: -10.0 cm/s = -0.1 m/s
If a flow velocity v = 5 m/s is measured, before the calculation of the derived quantities, it will be corrected as follows:
vcor = 1.1 · 5 m/s - 0.1 m/s = 5.4 m/s
Example
Slope: -1.0
Offset: 0.0
Only the sign of the measured values changes.
Notice!
The correction data will only be stored when a measurement is started. If the transmitter is switched off without starting a measurement, the entered correction data will be lost.

Limit of the signal amplification
In order to prevent disturbing and/or pipe wall signals (e.g., if the pipe has run empty) from being interpreted as useful signals, it is possible to define a max. signal amplification. If the signal amplification is greater than the max. signal amplification,
• the flow velocity will be marked as invalid. The physical quantity cannot be determined.
• a hash symbol (#) will be displayed after the unit of measurement (in case of a normal error, (?) is displayed).

• Select Special Funct.\SYSTEM settings\Measuring\Miscellaneous.
• Press ENTER until the menu item Gain threshold is displayed.
Special Funct.\SYSTEM settings\Measuring\Miscellaneous\Gain threshold\Fail if > 90 dB
• Enter for each measuring channel the max. signal amplification.
• Enter zero to measure without a limit of the signal amplification.
• Press ENTER.
The current value of the amplification (GAIN) can be displayed in the upper line in the program branch Measuring. If the
current value of the amplification is higher than the max. amplification, the current value is displayed with →FAIL!.
Notice!
The limit of the signal amplification is still activated after the deactivation of the SuperUser mode.
17.5
Upper limit of the sound speed
When the plausibility of the signal is evaluated, it will be checked whether the sound speed is within a defined range. The
used upper limit of the fluid sound speed is the greatest of the following values:
• fixed upper value, default: 1848 m/s
• value of the sound speed curve of the fluid at the operating point plus offset, default offset: 300 m/s
In the SuperUser mode, the values can be defined for fluids that are not contained in the data set of the transmitter.

17.6 Detection of long measurement failures
Example
fixed upper value of the sound speed (thresh.): 2007 m/s
offset: 600 m/s
value of the sound speed curve at the operating point: 1546 m/s
As 1546 m/s + 600 m/s = 2146 m/s is greater than the fixed upper value 2007, this value will be used as the upper limit
of the sound speed when the plausibility of the signal is evaluated.
It is possible to display the valid range for the sound speed (SS) in the lower line within the program branch Measuring
during the measurement. The second value (here: 2146 m/s) corresponds to the upper limit at the operating point.
